I just got my L7 installed with orion amp pushin it and now i get this wierd noise from my speakers when i step on the gas. It seems to get louder the more i accelerate and i think someone told me it cold be picking up ground. Before i got my sub and amp installed i only had 4 alpine speakers, components in the front and type rs in the back powered by an alpine amp. now i got that plus the L7 with the orion pushing that as well. what could be the noise im gettin? any help is appreciated.
